Abstract (en)
[origin: WO2015139760A1] A water distribution system (10) may include a pump assembly (30) and a controller (60) that controls operation of the pump assembly. The controller (60) may be configured to control cycling of the pump assembly on and off based on pressure and flow conditions detected in the system, track a first period of time, count a number of on/off cycles of the pump assembly, determine whether to make a state change based on the number of on/off cycles and the first period of time, and, in response to determining to make the state change, set a timer configured to count a second period of time that is longer than the first period of time and counting on/off cycles during discrete periods of time for the second period of time to initiate a fault response in response to a predetermined number of on/off cycles being detected during each discrete period of time during the second period of time or if the second period of time has lapsed, or initiate a recovery from the state change in response to the predetermined number of on/off cycles not being detected during at least one discrete period of time during the second period of time.
